Each bit features a 118-degree split-point tip that self-centers on contact, reducing walking and the need for a center punch on most surfaces. The set covers a minimum drill bit size of 1\/8 inch up to a maximum hole size of 3\/4 inch, making it a versatile option for drilling stepped, graduated holes in sheet metal, plastic, and thin-gauge materials. This set is dimensioned to the inch system and conforms to DIN specification standards. Electricians, HVAC technicians, and plumbers commonly keep a step drill set on hand for enlarging knockouts and punching clean holes in enclosures and junction boxes.\u003c\/p\u003e\n\u003cp\u003eThis step drill bit set is suited for trade professionals working on sheet metal fabrication, electrical panel work, conduit installations, HVAC equipment enclosures, and similar applications requiring clean, stepped holes without secondary deburring tools. The split-point geometry reduces thrust force and produces a cleaner entry hole compared to conventional point designs. Applicable to a range of thin-substrate materials encountered in residential and light commercial service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece set covering 1\/8 inch minimum to 3\/4 inch maximum hole size\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across metal and plastic substrates\u003c\/li\u003e\n  \u003cli\u003e118-degree split-point tip self-centers and reduces bit walking\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating to chip or flake during use\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN specification, inch measurement system\u003c\/li\u003e\n  \u003cli\u003eCompact set dimensions: 5.75 inches length, 1.65 inches width, 3.93 inches height\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose step drill bit set for use in standard 3\/8-inch or 1\/2-inch keyed or keyless drill chucks compatible with straight-shank step drill bits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eStep drill bits are typically used by electricians, HVAC technicians, and plumbers during rough-in and service work. Always secure the workpiece before drilling and use appropriate eye protection. Start at a low RPM to allow the split point to engage before increasing speed. Inspect bit cutting edges before use and do not force a worn bit, as heat buildup can harden the workpiece material and reduce bit life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Bit Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hole Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 3.93 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SDD43275023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730122539314,"sku":"SDD43275023","price":173.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e9d6c2fbed7bf466e06b63dc5799ecf.jpg?v=1788712092","url":"https:\/\/voomisupply.com\/products\/hertel-sdd43275023-step-drill-bit-set-3-pc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
